Hooking up in the college context: the event-level effects of alcohol use and partner familiarity on hookup behaviors and contentment

The current study examined hooking up experiences through event-level analyses, including the connections involving alcohol use, the extent of physical contact, and postevaluations of the hookup event. Participants were 828 college students (67.0% female). Of students who reported hooking up sometime within the past year (54.8%), chi-square analyses revealed that they were more likely to have been drinking when they met their partners the night of the hookup. Females who were drinking beforehand and females who met their partners that night were more likely to feel discontent with their hookup decisions. Among participants who consumed alcohol prior to their last hookup, a notable 30.7% of females and 27.9% of males indicated that they would likely not have hooked up with their partners had alcohol not been involved. Further, 34.4% of females and 27.9% of males indicated that they would not have gone as far physically if they had not been drinking. Among participants who reported both drinking beforehand and hooking up with unfamiliar partners, greater number of drinks consumed was associated with more advanced sexual behaviors. The current findings highlight the potential risks associated with alcohol use in the hooking up culture.

The Influence of Reflective Opposite-Sex Norms and Importance of Opposite-Sex Approval on Adjudicated Student Drinking: Theoretical Extensions and Implications

This study examines the salience and influence of reflective norms regarding opposite-sex friends, dating, and sexual partners on drinking behaviors of heterosexual college students sanctioned for violating the campus alcohol policy (i.e., adjudicated students). Results revealed that the level of importance placed on approval from the opposite sex is an important moderator for women but not for men. Selectively augmenting existing adjudicated student interventions with reflective normative feedback may be an effective intervention approach.

What are other parents saying? Perceived parental communication norms and the relationship between alcohol-specific parental communication and college student drinking

This study examined parents' normative perceptions of other college parents' alcohol-specific communication, and how parents' perceived communication norms and alcohol-specific communication relate to student drinking outcomes. A sample of 457 student-parent dyads were recruited from a midsize university. Students completed Web-based assessments of alcohol-related attitudes and behaviors. Parents completed alcohol-specific measures of communication norms and parent-child communication, including communication content (i.e., targeted communication) and frequency of communication. Results indicated that parents overestimated how much other parents talked to their college students about the frequency and quantity of alcohol use, but underestimated how often parents initiated conversations about alcohol. In a path model, perceived communication norms positively predicted both targeted communication and frequency of communication. Perceived communication norms and targeted communication negatively predicted students' attitude toward alcohol use. In contrast, more frequent communication predicted students holding more approving attitudes toward alcohol. The relationship between parents' perceived communication norms and students' drinking behaviors was mediated by the parental communication variables and student attitudes. Tests of indirect effects were undertaken to examine meditational processes. The findings underscore relations involving parental perceived communication norms and parents' own alcohol communication and their children's drinking outcomes. The complex relationships of different types of parental communication and student outcomes warrant further research.

RCT of web-based personalized normative feedback for college drinking prevention: are typical student norms good enough?

OBJECTIVES

Personalized normative feedback (PNF) interventions are generally effective at correcting normative misperceptions and reducing risky alcohol consumption among college students. However, research has yet to establish what level of reference group specificity is most efficacious in delivering PNF. This study compared the efficacy of a web-based PNF intervention using 8 increasingly specific reference groups against a Web-BASICS intervention and a repeated-assessment control in reducing risky drinking and associated consequences.

METHOD

Participants were 1,663 heavy-drinking Caucasian and Asian undergraduates at 2 universities. The referent for web-based PNF was either the typical same-campus student or a same-campus student at 1 (either gender, race, or Greek affiliation), or a combination of 2 (e.g., gender and race), or all 3 levels of specificity (i.e., gender, race, and Greek affiliation). Hypotheses were tested using quasi-Poisson generalized linear models fit by generalized estimating equations.

RESULTS

The PNF intervention participants showed modest reductions in all 4 outcomes (average total drinks, peak drinking, drinking days, and drinking consequences) compared with control participants. No significant differences in drinking outcomes were found between the PNF group as a whole and the Web-BASICS group. Among the 8 PNF conditions, participants receiving typical student PNF demonstrated greater reductions in all 4 outcomes compared with those receiving PNF for more specific reference groups. Perceived drinking norms and discrepancies between individual behavior and actual norms mediated the efficacy of the intervention.

CONCLUSIONS

Findings suggest a web-based PNF intervention using the typical student referent offers a parsimonious approach to reducing problematic alcohol use outcomes among college students.

Are they all the same? An exploratory, categorical analysis of drinking game types

Drinking games have become a ubiquitous part of the college student drinking culture and are associated with drinking to intoxication and increased alcohol consequences. Contemporary research commonly considers drinking games holistically, with little to no consideration to the different drinking game types. The current study describes the creation of a novel DG categorization scheme and reports differences between DG categories. Participants were 3421 college students (58% female) who completed online surveys. Based on participant responses, 100 distinct drinking games were identified and defined. Two student focus groups were conducted in which drinking game definitions and rules were verified by students. Drinking games were then categorized into five mutually exclusive categories: Targeted and Skill games, Communal games, Chance games, Extreme Consumption games, and Even Competition games. Finally, the frequency of games played in each category and typical player profiles were reported. Differences in peak drinks and frequency of specific alcohol consequences were documented according to game categories. The findings provide a novel drinking game categorization scheme and an exploratory analysis of basic differences between game categories.

Do as I Say, Not as You Perceive: Examining the Roles of Perceived Parental Knowledge and Perceived Parental Approval in College Students' Alcohol-Related Approval and Behavior

Objective

This study examined college students' accuracy in their perceptions of parental approval of engaging in various alcohol-related behaviors, evaluated the mediational role of student approval in the relation between perceived parental knowledge and drinking, and determined the extent to which perceived parental approval moderated the relation between perceived parental knowledge and student approval.

Design

Participants were 264 college student-parent dyads who completed independent online surveys.

Results

Students overestimated parental approval of the child drinking, and parents were more approving of a "typical student" drinking than they were of their own child drinking. Student approval mediated the relation between perceived parental knowledge and student drinking, controlling for other relevant predictors. Perceived parental approval moderated the relation between perceived parental knowledge and student approval, controlling for other notable predictors.

Conclusion

Parents continue to influence their child's alcohol-related attitudes and behaviors, even while in college.

Event-specific risk and ecological factors associated with prepartying among heavier drinking college students

Using event-specific data, the present study sought to identify relevant risk factors and risky drinking patterns associated with prepartying. Analyses focused on drinking outcomes as a function of drinking game playing and the social context on occasions where prepartying did and did not occur. This research utilized a representative two-site sample of prepartiers who also reported a heavy episodic drinking event in the past month (n=988). Results revealed that during a preparty event, participants drank significantly more, reached higher blood alcohol levels (BALs), and experienced significantly more negative consequences compared to the last occasion that they drank but did not preparty. Students who played drinking games when they prepartied had higher BALs and experienced more negative consequences than those who did not play drinking games. Whether females prepartied in a single-sex or coed setting had little effect on their BALs. For males, however, their BALs were greater when they prepartied in a coed setting compared to a single sex setting. Moreover, participants reported more negative consequences when they prepartied in a coed setting than in a single-sex setting. Finally, regression analyses demonstrated that participants' BAL, frequency of prepartying, and the interaction between BAL and frequency of prepartying all uniquely contributed to the prediction of event-specific alcohol-related negative consequences. As BAL increased, the number of negative consequences increased more sharply for those who prepartied infrequently, compared to those who prepartied frequently. Analyses were examined as a function of gender which revealed important gender effects and interactions. Interventions can be designed to intervene with high-risk prepartiers by using BAL education emphasizing the impact of time-limited prepartying drinking.

I can play all night: examining the relationship between perceived tolerance and drinking game alcohol consumption

The present study examined the impact of perceived tolerance to alcohol on maximum alcohol consumption while playing drinking games. Participants were student drinkers (N=3,546) from two west coast universities. Among these students, 69.2% (n=2,290) reported playing a drinking game in the past month. Analyses demonstrated game players had higher perceived tolerances, and consumed more alcohol than non-game players. A regression model revealed that higher levels of perceived tolerance were related to increased maximal alcohol consumption while playing drinking games. Study limitations and implications for future research are discussed.

Measuring college students' motives behind prepartying drinking: development and validation of the prepartying motivations inventory

Drinking motives are vital in identifying risk factors and better understanding alcohol-related outcomes. However, context-specific motivations could provide greater motivational perspective on high-risk context-specific alcohol use behaviors such as prepartying (consuming alcohol prior to attending one's intended destination) than general alcohol motivations. In the current study, students' open-ended responses to reasons for prepartying were collected from a large diverse sample (n=2497), and the most commonly offered reasons were used to create a prepartying motivations inventory (PMI) that was then administered to a different sample (n=1085). A split-half validation procedure was used for the purpose of evaluating the PMI's factor structure. Exploratory and confirmatory factor analyses yielded a final 16-item measure consisting of four distinct, but inter-related, factors: Interpersonal Enhancement, Situational Control, Intimate Pursuit, and Barriers to Consumption. Internal consistency reliability, discriminant validity, and criterion-related validity were empirically demonstrated. Results support the notion that individuals preparty for a variety of reasons that are distinct from general motives. Researchers are encouraged to use the PMI in future research with young adults to provide further understanding of prepartying behavior and its psychosocial correlates.

Prevalence, social contexts, and risks for prepartying among ethnically diverse college students

Prepartying, also known as pre-gaming, has emerged as a high-risk drinking event among U.S. college students. Research on factors related to prepartying behavior is in its relative infancy. The present study provides prevalence rates for prepartying across ethnic groups and examines how social context (whether prepartying took place with primarily male, female, or coed groups) and demographic factors may influence prepartying behavior. Participants were students from two West Coast universities (N=2546) whom identified as White, Asian and Pacific Islander American (APIA), Hispanic/Latino(a), or African American. The percentage of students who reported prepartying at least once in the past month, as well as the frequency and number of drinks consumed for prepartying occasions, varied by ethnic group and sex. A greater proportion of White students (60%) reported prepartying than Hispanic/Latino(a) (52%), African American (44%), and APIA (37%) students, though Hispanic/Latino(a) students who prepartied did so as often and consumed similar amounts of alcohol as White prepartiers. Across all ethnic groups, females who reported prepartying in coed groups consumed significantly more drinks than those who prepartied in primarily female groups. Finally, prepartiers within all ethnic groups consumed more drinks per week and experienced a higher number of alcohol-related consequences than non-prepartiers. The results suggest that future research and prevention programs should target prepartying and other high-risk events in at-risk students of ethnically diverse backgrounds and also consider the effects of gender in prepartying contexts on alcohol use.

Estimates and influences of reflective opposite-sex norms on alcohol use among a high-risk sample of college students: exploring Greek-affiliation and gender effects

Reflective opposite sex norms are behavior that an individual believes the opposite sex prefers them to do. The current study extends research on this recently introduced construct by examining estimates and influences of reflective norms on drinking in a large high-risk heterosexual sample of male and female college students from two universities. Both gender and Greek-affiliation served as potential statistical moderators of the reflective norms and drinking relationship. All participants (N=1790; 57% female) answered questions regarding the amount of alcohol they believe members of the opposite sex would like their opposite sex friends, dates, and sexual partners to drink. Participants also answered questions regarding their actual preferences for drinking levels in each of these three relationship categories. Overall, women overestimated how much men prefer their female friends and potential sexual partners to drink, whereas men overestimated how much women prefer their sexual partners to drink. Greek-affiliated males demonstrated higher reflective norms than non-Greek males across all relationship categories, and for dating partners, only Greek-affiliated males misperceived women's actual preferences. Among women however, there were no differences between reflective norm estimates or the degree of misperception as a function of Greek status. Most importantly, over and above perceived same-sex social norms, higher perceived reflective norms tended to account for greater variance in alcohol consumption for Greeks (vs. non-Greeks) and males (vs. females), particularly within the friend and sexual partner contexts. The findings highlight that potential benefits might arise if existing normative feedback interventions were augmented with reflective normative feedback designed to target the discrepancy between perceived and actual drinking preferences of the opposite sex.

Global sleep quality as a moderator of alcohol consumption and consequences in college students

The authors examined the relationship between global sleep quality and alcohol risk, including the extent to which global sleep quality moderated the relationship between alcohol use and drinking-related consequences. Global sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and alcohol-related consequences were assessed using the Rutgers Alcohol Problem Index (RAPI). The sample consisted of 261 college students (61.3% female, 58.2% Caucasian) who completed online surveys. Using a four-step hierarchical multiple regression model, global sleep quality was found to predict alcohol consequences, over and above assessed covariates (demographics and weekly drinking). Further, global sleep quality emerged as a strong moderator in the drinking-consequences relationship such that among heavier drinkers, those with poorer global sleep quality experienced significantly greater alcohol-related harm. Campus health education and alcohol interventions may be adapted to address the importance of maintaining a healthy lifestyle, both in terms of healthful sleeping and drinking behaviors, which appear to play a strong synergistic role in alcohol-related risk.

Poor adjustment to college life mediates the relationship between drinking motives and alcohol consequences: a look at college adjustment, drinking motives, and drinking outcomes

The current study examined whether the relationship between drinking motives and alcohol-related outcomes was mediated by college adjustment. Participants (N=253) completed an online survey that assessed drinking motives, degree of both positive and negative college adjustment, typical weekly drinking, and past month negative alcohol-related consequences. Structural equation modeling examined negative alcohol consequences as a function of college adjustment, drinking motives, and weekly drinking behavior in college students. Negative college adjustment mediated the relationship between coping drinking motives and drinking consequences. Positive college adjustment was not related to alcohol consumption or consequences. Positive reinforcement drinking motives (i.e. social and enhancement) not only directly predicted consequences, but were partially mediated by weekly drinking and degree of negative college adjustment. Gender specific models revealed that males exhibited more variability in drinking and their positive reinforcement drinking motives were more strongly associated with weekly drinking. Uniquely for females, coping motives were directly and indirectly (via negative adjustment) related to consequences. These findings suggest that interventions which seek to decrease alcohol-related risk may wish to incorporate discussions about strategies for decreasing stress and increasing other factors associated with better college adjustment.

Examining the relationships between acculturation orientations, perceived and actual norms, and drinking behaviors of short-term american sojourners in foreign environments

As little research has examined factors influencing increased and heavy drinking behavior among American sojourners abroad, this study was designed to examine how acculturation orientations (i.e., separation versus assimilation), host country per capita drinking rates, and perceptions about the drinking behavior among other sojourners and natives in the host country predicted alcohol risk abroad. A sample of 216 American college students completing study abroad programs completed a pre-abroad questionnaire to document their pre-abroad drinking levels, followed by a post-return questionnaire to assess drinking while abroad, acculturation orientations and perceived norms of drinking behavior within the foreign environment. A dichotomous variable was created to compare United States (U.S.) per capita drinking rates with those of the host country. Hierarchical repeated-measures ANOVAs examined the changes in drinking from pre-abroad to abroad levels. Participants studying in countries with higher drinking rates than the U.S. and those with higher perceptions about the drinking behavior in the country increased their drinking to a greater extent. Those with higher separation acculturation orientations and greater perceptions drank at heavier levels while abroad. Participants with a greater assimilation orientation and higher perceptions about native drinking, as well as those with a greater separation orientation and higher perceptions about other students' alcohol use drank the heaviest while abroad. These findings have implications for future preventive work with American students and other sojourning groups to promote pre-abroad knowledge of more accurate drinking norms and greater engagement in the culture to potentially prevent increased and heavier drinking.

Descriptive drinking norms: For whom does reference group matter?

OBJECTIVE

Perceived descriptive drinking norms often differ from actual norms and are positively related to personal consumption. However, it is not clear how normative perceptions vary with specificity of the reference group. Are drinking norms more accurate and more closely related to drinking behavior as reference group specificity increases? Do these relationships vary as a function of participant demographics? The present study examined the relationship between perceived descriptive norms and drinking behavior by ethnicity (Asian or White), sex, and fraternity/sorority status.

METHOD

Participants were 2,699 (58% female) White (75%) or Asian (25%) undergraduates from two universities who reported their own alcohol use and perceived descriptive norms for eight reference groups: "typical student"; same sex, ethnicity, or fraternity/sorority status; and all combinations of these three factors.

RESULTS

Participants generally reported the highest perceived norms for the most distal reference group (typical student), with perceptions becoming more accurate as individuals' similarity to the reference group increased. Despite increased accuracy, participants perceived that all reference groups drank more than was actually the case. Across specific subgroups (fraternity/sorority members and men) different patterns emerged. Fraternity/sorority members reliably reported higher estimates of drinking for reference groups that included fraternity/ sorority status, and, to a lesser extent, men reported higher estimates for reference groups that included men.

CONCLUSIONS

The results suggest that interventions targeting normative misperceptions may need to provide feedback based on participant demography or group membership. Although reference group-specific feedback may be important for some subgroups, typical student feedback provides the largest normative discrepancy for the majority of students.

Parents know best, but are they accurate? Parental normative misperceptions and their relationship to students' alcohol-related outcomes

OBJECTIVE

Parents often look to other parents for guidance, but how accurate are their perceptions? Expanding on existing normative literature to include parents of college students, this study first sought to determine whether parents accurately estimated the attitudes of other parents concerning their college student's alcohol-related behaviors. The effect of these (mis)perceived injunctive norms on the alcohol-related attitudes and behaviors of the parents' own children was then examined.

METHOD

Participants were 270 college student-parent dyadic pairs who completed independent online surveys. The student sample was 59% female; the parent sample was 78% female.

RESULTS

A structural equation model demonstrated that parents significantly overestimated other parents' approval of alcohol use by their respective child and, further, that these misperceptions strongly influenced parental attitudes toward their own child's drinking. Parental attitudes were subsequently found to be significantly associated with their child's attitudes toward drinking but were only marginally associated with the child's actual drinking, thereby underscoring the mediational effect of the child's attitudes.

CONCLUSIONS

This is the first study to document the influence of parental normative misperceptions regarding alcohol use by their college-age children, reinforcing the importance of parental attitudes on children's alcohol-related attitudes and behaviors in college. These findings support the need to complement student-based interventions with parent-based interventions aimed at increasing parental awareness and involvement. Further, the current findings indicate that normative interventions targeting parents offer a promising avenue by which to indirectly and positively influence college students' alcohol use.

Comparing Greek-Affiliated Students and Student Athletes: An Examination of the Behavior-Intention Link, Reasons for Drinking, and Alcohol-Related Consequences

While affiliation with Greek fraternities/sororities and intercollegiate athletic teams is associated with heavier drinking (Meilman et al., 1999), few studies have compared reasons for drinking among these groups. A sample of 1,541 students, identifying as either Greeks or athletes, completed an online survey. Athletes were significantly higher than Greeks on conformity reason for drinking. Tests of independent correlations indicated the magnitude of the past behavior to intention link was considerably stronger for Greeks. Greeks experienced significantly more social problems from drinking. Several group by gender ANOVA models found significant main effects with highest drinking rates, usually among Greek males, and lowest among female athletes. Understanding these specific group differences informs recommendations for group-specific and tailored educational interventions, which are discussed.

Direct and indirect effects of injunctive norms on marijuana use: the role of reference groups

OBJECTIVE

Little work has evaluated the relationship between injunctive norms and marijuana use. This study sought to establish whether misperceptions exist between perceived injunctive norms of typical college students and the actual approval level of the students. We also examined respondents' perceptions of which groups (typical student, close friends, and parents) were the most and least approving of marijuana. These variables were then applied to an explanatory model to assess their relationships with marijuana use.

METHOD

Participants were 3,753 students (61% female) randomly recruited from two West Coast campuses. Participants were asked about their own marijuana use and their own approval toward marijuana. Injunctive norms were assessed by asking respondents about their perceptions of how much other reference groups approved of marijuana.

RESULTS

Students overestimated the extent to which the typical student approves of marijuana use. A path model showed that perceived approval of both close friends and parents predicted actual/self-approval, which in turn was most predictive of personal marijuana use. Perceptions of typical-student and close friends' approval also directly predicted one's own use, whereas the path from parental approval to marijuana use was fully mediated by one's own approval.

CONCLUSIONS

Findings suggest that perceived injunctive norms may function differently with respect to marijuana use than they do with respect to alcohol use and raise questions about how to incorporate social-normative information into marijuana interventions.

"This would be better drunk": alcohol expectancies become more positive while drinking in the college social environment

The current study examined whether drinking and/or presence in the college social environment led to augmented positive alcohol expectancies among college students (N=225). Participants were approached during popular drinking nights as they exited events at which alcohol was consumed or in front of their residence as they returned home. Participants completed a brief questionnaire that included an assessment of demographics, breath alcohol concentration (BrAC), and positive expectancies. Within 48 h of baseline assessment, participants received via email a follow-up survey that re-assessed positive expectancies while sober. Positive sexual expectancies were more strongly endorsed while drinking in the college social environment for both males and females, while males also reported heightened liquid courage expectancies. In addition, positive expectancies were more strongly endorsed at higher doses of alcohol for males but not females. These findings suggest that interventions which seek to prevent alcohol abuse by targeting alcohol expectancies may wish to challenge positive expectancies in naturalistic college social settings.

Comparing injunctive marijuana use norms of salient reference groups among college student marijuana users and nonusers

Marijuana is the most commonly used illicit drug among college students and has the potential for various negative outcomes. Perceptions of what constitutes typical approval/acceptability of a reference group (i.e. injunctive social norms) have been shown to have strong utility as predictors of health-risk behaviors in the college context, yet this construct remains significantly understudied for marijuana use despite its potential for use in social norms-based interventions. The current research evaluated individuals' marijuana approval level and their perceptions of others' marijuana approval level (i.e. injunctive norms) for various reference groups (typical student on campus, one's close friends, and one's parents) as a function of individual user status (abstainers, experimenters, occasional users, and regular users). A diverse sample of 3553 college students from two universities completed an online survey. Among all user status groups, individual approval yielded mean scores paralleling that of perceived close friends' approval and all groups were relatively uniform in their perception of typical students' approval. Higher levels of marijuana use tended to produce higher endorsements of individual approval, perceived close friends' approval, and perceived parental approval. Among occasional and regular users, there were no differences between one's own approval level for use and the perceptions of close friends' approval, nor did they think the typical student was more approving than themselves. Abstainers and experimenters, however, perceived typical students and close friends to have more permissive attitudes than themselves. Implications and future directions for research regarding the role of injunctive marijuana use norms in the development of social norms intervention are discussed.

How drunk am I? Misperceiving one's level of intoxication in the college drinking environment

One effective event-level index that can assist in identifying risky intoxication levels among college students is blood alcohol concentration (BAC). Despite widespread exposure to BAC information, doubt exists as to whether American college students can accurately estimate their own BAC level or drinking behaviors while intoxicated. This study assessed whether students can accurately guesstimate their BAC level and drinking behaviors used to estimate BAC (eBAC) while drinking in social college settings. Participants (N = 225; 56.4% male) consisted of emerging adults attending either a 2- or 4-year college who had at least one alcoholic drink within the 2 hr before assessment. Participants were approached at night when returning from parties and/or alcohol-serving establishments. They completed an initial questionnaire, gave a breath sample to assess breath alcohol content, and then completed an online follow-up questionnaire within 48 hr of baseline assessment. Participants at lower levels of intoxication tended to slightly overestimate their BAC level, while those at higher levels tended to markedly underestimate their BAC level. In addition, discrepancies among breath alcohol content, guesstimated BAC, and eBAC were found as a function of gender. Lastly, differences in eBAC scores did not differ when drinking behaviors were obtained via in vivo versus retrospective methodology. Findings suggest that college students generally have difficulty assessing their BAC level and drinking behaviors while drinking in the college social setting. This study offers particular insight for research relying on estimates of BAC as well as interventions utilizing BAC education.

Group identification as a moderator of the relationship between perceived social norms and alcohol consumption

Previous research has shown that social norms are among the strongest predictors of college student drinking. Among college students, perceiving that others drink more heavily than themselves has been strongly and consistently associated with heavier drinking. Research has also shown that the more specifically others are defined, the stronger the association is with one's own drinking. In the current research, we evaluated whether group identification as defined by feeling closer to specific groups moderates the associations between perceived drinking norms in the group and one's own drinking. Participants included 3,752 (61% female) students who completed online assessments of their perceived drinking norms for 4 groups of students on their campus and identification with each group and participants' own drinking behavior. Results indicated that greater identification with same-sex students, same-race students, and same-Greek-status students was associated with stronger relationships between perceived drinking norms in the specific groups and own drinking.

WARMING UP AND STAYING LOOSE: THE PREVALENCE, STYLE, AND INFLUENCE OF PREPARTYING BEHAVIOR AND DRINKING GAMES AMONG INTERCOLLEGIATE ATHLETES

This study investigates the prevalence and influence of prepartying behavior along with the co-occurrence of drinking game participation among a sample of Division 1 student-athletes (N = 568) from two institutions. Results indicate that 67% (n =382) of the sample had prepartied in the past month, with 36% (n = 205) of the overall sample also having typically played drinking games in that context. Individuals that typically played drinking games while prepartying reported higher risk on the main outcome variables of overall past month alcohol consumption, prepartying-specific drinking behavior, and negative alcohol-related consequences than the prepartying-only group, which in turn evidenced higher consumption and risk when compared to the non-prepartying group. Moreover, males, as compared to females, demonstrated elevated scores on all outcome variables. Implications include the potential to help inform both prevention and intervention efforts among student-athletes.

Underestimations of blood alcohol concentration predict event-specific negative consequences

The current study sought to establish in vivo misperception of blood alcohol concentration (BAC) as a predictor of event-specific alcohol-consumption-related negative consequences. During spring 2010, 225 (56.4% male) college students, who had consumed at least one alcoholic drink within the 2 hr prior to assessment, completed a questionnaire, gave a breath sample to assess breath alcohol content, and later completed a follow-up questionnaire. Underestimation of BAC was predictive of event-specific, alcohol-consumption-related negative consequences, over and above other factors including total drinks consumed. This study highlights the need for more focused BAC education strategies at American universities.
